But outdoors your muscles really get a better workout viewing objects miles away and not just the next wall.
I think too much screen time might make your eyes feel tired, LCDs vs eink vs paper might make some not sleep as well (although neither have ever bothered me and I've had bad eyesight all my life, I'm very farsighted). I don't believe using your eyes to read a lot makes you blind or even causes any eye disease no matter what medium you read from, book or screen.

Not to mention kids these days get a lot more junk in their diet than we did back in the day. They talk about vitamin enriched foods but at the same time the amount of sugar, salt and bad fats in foods today has to have an impact on a person as a whole. Certainly it doesn't help prevent diabetes which can and often does affect the eyes as much as anything.
